- Abstract: Objective To explore the serial mediated role of core self-evaluation and emotion regulation strategies in the relationship between extraversion personality characteristics and loneliness among college students.Methods An offline survey was conducted via Questionnaire Star with 507 college students using the Extraversion Subscale of the Eysenck Personality Questionnaire-Revised Short Scale(EPQ-R Short Scale),the Core Self-Evaluations Scale(CSES),the Emotion Regulation Questionnaire(ERQ),and the Loneliness Scale(UCLA).Data collection was completed through the Wenjuanxing(Questionnaire Star)online platform.Correlation analysis and structural equation modeling(SEM)were employed to examine the effects of extraversion,core self-evaluation,and emotion regulation strategies on loneliness.Results Extraversion was positively correlated with core self-evaluation(r=0.39,P＜0.01)and the cognitive reappraisal dimension of emotion regulation(r=0.23,P＜0.01),but negatively correlated with the expressive suppression dimension of emotion regulation(r=-0.21,P＜0.01)and loneliness(r=-0.45,P＜0.01).Core self-evaluation was positively correlated with cognitive reappraisal(r=0.43,P＜0.01),but negatively correlated with expressive suppression(r=-0.24,P＜0.01)and loneliness(r=-0.60,P＜0.01).Additionally,cognitive reappraisal was negatively correlated with loneliness(r=-0.42,P＜0.01),whereas expressive suppression was positively correlated with loneliness(r=0.35,P＜0.01).Mediation analysis revealed a serial mediation effect,where core self-evaluation and cognitive reappraisal jointly mediated the relationship between extraversion and loneliness(effect size=-0.034,accounting for 7.9％ of the total effect).Similarly,core self-evaluation and expressive suppression also served as serial mediators(effect size=-0.017,accounting for 3.9％ of the total effect).Conclusion Extraversion influences college students' loneliness through both the mediating roles of core self-evaluation and expressive suppression,as well as the serial mediation effects involving core self-evaluation combined with cognitive reappraisal or expressive suppression.This suggests that intervening in core self-evaluation and emotion regulation strategies can effectively mitigate loneliness among college students.
